| 摘要: |
| 以一年生丹桂枝条为材料，探索桂花非试管快速繁殖最佳条件。用不同浓度吲哚乙酸（IBA）浸泡插条基部，对比不同实验组材料的生根率。实验结果显示，200 mg/L的IBA处理的桂花枝条，在定时控制喷雾条件下，插后55 d的生根率和成苗率达100%。本研究对加快桂花培育速度、对深化桂花快繁技术研究具有重要意义。 |

| Abstract: |
| The non-test tube rapid propagation technology system of Osmanthus fragrans was studied using the annual Dangui branches as explants. The roots of the cut branches were treated with different concentrations of indolebutyric acid (IBA) to analyse the rooting rates of different explants. Treated Osmanthus fragrans branches with IBA at the concentration of 200 mg/L, the results showed that the rooting and seedling survival rate was up to 100% under the cultivational conditions of controlled mist spraying system by the end of 55th day. The results are of great significance for accelerating the cultivation speed of osmanthus fragrans and deepening the research on micropropagation of osmanthus fragrans. |
